I Specification of Letters Patent. I Application filed April 6- 1907. Serial No, 366.761.

Patented Feb. '4; 1908.

Be it known that I, FRED L. ADAMS, citi-- zen of the United States, residing at Prophetstown, in the county-of Whiteside and State of Illinois, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specification.

This invention contemplates certain new and usefulimprovements in ournal bearings or boxes, and relates particularly to an irnproved construction of bearing for the reel shaft of a lawn mower. f 7.

The invention has for its object an irn--- proved bearing, the construction and arrangement of which will preventthebearing block from rolling or turning overin the journal box, and further objects are to pro vide springs so arranged as to hold the block rigidly in place and yet permit sufficient freedom for the block to adjust itselfto alinenient with the shaft;

\Vith this and other objects in view as will more fully appear as the description pro coeds, the invention consists in. certainconstructions, arrangements and combinations of the parts which I shall now hereinafter fully describe and then point out the novel features in the appended claims.

For a full description of the invention and the merits thereof -and also to acquire knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is aperspective view of a l'awn mower provided with my improved journal bearings for the reel shaft. Fig. 2 is a longitudinal sectional view of both boxes with the shaft journaled therein. Fig. 3 is a transverse sectional view, on an enlarged scale, the section being taken on the line 3-301? Fig. 2. 4 is a-detail perspective view of one of thebearing blocks.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

the numeral 1 designates the side plates or heads of a lawn mower to which my invention is applied,

said heads being formed with preferably integral journal boxes 2 extending inwardly, and each formed with a substantially ree tangular chamber to receive the bearing block.

into and projects through the boxes I My improved bearing block 4 which is adapted to encircle the ends of the shaft 3, is provided with a circular bore to receive-the shaft and is split by means of the formation of a longitudinal opening 5 therein, the opening, extending throughout its length. The block 4. is rectangular and substantially square in cross section at its middle, and tapers, with a rounded. formation. towards the ends The opening 5 is preferably oblique to the horizontal plane of the block, as best seen in Fig. The block 4 is formed withia tension screw 8. is intended to work in. said opening, said screw being inserted through an aperture 9 formedin the upper wall of the box 10 and 11 designate springs which are preferably of the leaf variety, and which are interposed between two adjacent walls of the box and the block, preferably the lower and rear walls, and the function of these springs is to hold the block rigidly in place and yetin a sufliciently yielding manner as to permit it to adjust itself to alinement with the shaft By means of the tension screw 8, the block may be closed or drawn together so as to iit the shaft and corn-- pensate for any wear.

tion with. the accompanying drawings, it will be seen that by means of the-springs 10 and 1'1, the block will be held firmly against the .walls of the box opposite said springs and thereby prevent any shake or shifting of the block or bearing, while the tapered formation of the block with its square middle iortion, insures that the block will be neld firmly in the box and yet be permitted. to l rock, to adjust itself to the shaft without any possibility of its rolling or turning over in the journal box.
